TitrePosterior ciliary arterial system occlusion after treatment for epistaxis
ButTo report a case of iatrogenic cilioretinal artery occlusion and choroidal ischemia after embolization of the sphenopalatine artery.
MéthodesA 58-year-old man was referred for a severe visual loss in the left eye at awakening from general anaesthesia. He had undergone a selective embolization of the left sphenopalatine
artery with 300-500 ym EmboGold® Microspheres for an idiopathic refractory posterior epistaxis.
RésultatsFundus examination showed a pale edema in the inter-papillo-macular area, sign of cilioretinal artery occlusion in the left eye. Fluorescein angiography revealed delayed cilioretinal artery perfusion and extensive areas of choroidal hypoperfusion. A variable number of anastomoses exist between branches of the internal and external carotid arteries carrying a risk of neurological accidents during embolization when embolic material inadvertently enters the internal carotid artery or its first collateral branch, the ophthalmic artery.
ConclusionThis case shows that posterior ciliary arterial system occlusion combining cilioretinal
artery occlusion and choroidal hypoperfusion, can occur as complication of epistaxis treatment. Ophthalmologists and otorhinolaryngologists need to be aware of the risk of this rare but possible complication.
